Abstract
For the development of tungsten substitute materials for cemented carbide (WC-Co), new titanium carbonitride (Ti(C,N) base cermets are studied and developed to applied cutting tools and wear resistant tools. New carbonitride solid solution , (Ti,M)(C,N) [M: transition metal] as hard material in cermets is needed to improve the properties of cermets. In order to control the microstructure of cermets, preparation of fine and homogeneous powder is required. The effect of starting materials on the particle size of carbonitrides was studied.
